Ladezeitrechner

Berechnen Sie, wie lange das Laden eines Elektrofahrzeugs bei gegebener Ladeleistung dauert.

Einführung

Charging Time Calculator — Calculate how long it takes to charge an EV given charger power. Enter Current energy (kWh), Target energy (kWh), Charger power (kW), Efficiency (0-1) to get an instant, accurate result.

Formel

Charging time (hours) = (target kWh − current kWh) / charger power (kW) / charging efficiency.

Schritt für Schritt

  1. Enter the Current energy (kWh).
  2. Enter the Target energy (kWh).
  3. Enter the Charger power (kW).
  4. Enter the Efficiency (0-1).
  5. Click Calculate to see your result instantly.

Praxisbeispiel

Example: With Current energy (kWh) = 10, Target energy (kWh) = 60, Charger power (kW) = 7.2, Efficiency (0-1) = 0.9, the Charging Time Calculator gives a result of 7.716.

Häufig Gestellte Fragen

Why is my actual charging time longer than this estimate?
Charging speed typically tapers as the battery fills (especially past ~80% on DC fast charging), which this simple linear formula doesn't model.
Should I use my car's max charge rate or the charger's rated power?
Use whichever is lower — charging speed is capped by the smaller of the two.
What inputs does the Charging Time Calculator need?
You'll need to provide: Current energy (kWh), Target energy (kWh), Charger power (kW), Efficiency (0-1). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Charging Time Calculator?
The Charging Time Calculator applies the formula exactly as calculated — Charging time (hours) = (target kWh − current kWh) / charger power (kW) / charging efficiency. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Charging Time Calculator free to use?
Yes, the Charging Time Calculator is completely free, requires no signup, and runs instantly in your browser.

Über Ladezeitrechner

The Charging Time Calculator uses a real, verifiable formula — Charging time (hours) = (target kWh − current kWh) / charger power (kW) / charging efficiency. — so results are accurate every time, not an approximation.
